Despite advances in methodology for m6A mapping the applicability of current methods is limited by the need for large amounts of input material. We develop a sensitive picogram scale m6A RNA immunoprecipitation and sequencing picoMeRIP seq method also suitable for single cell scMeRIP seq. We validate the down scaling of the method by profiling m6A from picogram amounts of mouse liver polyA selected RNA mouse embryonic stem cells and zebrafish zygotes. We provide proof of principle of m6A profiling in single mouse oocytes and preimplantation embryos. Our work opens a new avenue for studying m6A in single cells and scarce cell types in a transcriptome wide manner. Overall design: Transcriptome wide m6A maps were generated from zebrafish and mouse samples as below. 11 zebrafish zygote samples: 3 biological replicates for 10 zygotes 3 biological replicates for 5 zygotes and 5 biological replicates for single zygote. 6 mouse liver polyA selected RNA samples: 10 ng 1 ng and 100 pg; 2 biological replicates for each amount. 9 mouse embryonic stem cell R1 cell line from ATCC SCRC 1011 samples: 1000 cells 100 cells and 10 cells; 3 biological replicates for each amount. 3 spike in RNA control add 0.001 fmol Gaussia luciferase/GLuc with m6A modification and 0.001 fmol Cypridina luciferase/CLuc without xxx modification into the 12 ng polyA selected RNAs related samples: 12 ng polyA selected RNA from mouse liver; 6 ng polyA selected RNA from mouse liver and 6 ng polyA selected RNA from wild type/WT mouse embryonic stem cells from Geula S. et al. Science 2015; and 6 ng polyA selected RNA from mouse liver and 6 ng polyA selected RNA from Mettl3 knock out/KO mouse embryonic stem cells from Geula S. et al. Science 2015. 12 single mouse oocyte and embryo samples: oocytes at germinal vesicle GV and metaphase II MII stages and embryos at zygote 2 cell 8 cell and blastocyst stages; 2 biological replicates per developmental stage. The pooled Input samples for GV oocyte GSM5746922 zygote GSM5746930 2 cell GSM5746911 and 8 cell GSM5746914 stages can be found in GSE192440.		pubmed:37349523		ZF zygote IP 1cell Rep1	GSM5599721		tissue:ZF zygote IP 1cell\|developmental stage:Zygote\|molecule subtype:rRNA free RNA	ZF zygote IP 1cell Rep1	Quality of raw reads was assessed using FastQC v0.11.8 and sequencing adapters were trimmed using Cutadapt v1.8.1 if clear adapter signal was detected at the three primeend of the reads.

Trimmed reads were aligned to the reference genome mm10 for mouse danRer11 for zebrafish using HISAT2 v2.1.0 with the parameter “ 5 8 no mixed no discordant”. Multiply aligned reads were discarded as indicated by HISAT2. PCR duplicates were removed using Samtools v1.9. The read pairs that overlapped with ribosomal RNAs were removed using BEDTools v2.28.0. Genome coverage bigWig files bin size = 10 bp normalized by RPKM were generated by deepTools v3.2.0 bamCoverage with the parameter “ bs 10 normalizeUsing RPKM”.

ZF zygote IP 1cell	For mouse GV oocyte collection 8 wpf C57BL6/N females were injected with 5 units U of pregnant mare serum gonadotropin PMSG. post 48 hours ovaries were dissected and oocytes were isolated by puncturing the follicles. The procedure was carried out in M2 medium Sigma supplemented with 0.2 mM of the cyclic nucleotide phosphodiesterase inhibitor 3 Isobutyl 1 methylxanthine IBMX Sigma to prevent the oocytes from further progress to germinal vesicle breakdown GVBD. The cumulus cells were gently removed by pipetting and the oocytes were briefly exposed to acidic Tyrode's solution Sigma to remove the zona pellucida followed by three washes in M2 medium. For mouse MII oocyte collection 4 wpf 5 wpf C57BL6/N females were injected with 5 U of PMSG followed by 5 U of human chorionic gonadotropin hCG 45 hours later. The oviducts were dissected 20 22 hours later and transferred to a clean dish containing M2 medium. The oviduct ampulla was identified under a stereomicroscope to isolate MII oocytes containing the cumulus mass. The oocytes were treated with 0.3 mg/ml hyaluronidase dissolved in M2 medium to remove the cumulus cells and then exposed to acidic Tyrode's solution for a few seconds to remove the zona pellucida followed by three washes in M2 medium. For mouse early embryo collection 8 wpf C57BL/6N females were superovulated by hormone injection 5 U PMSG followed by 5 U hCG 45 hours later and transferred to cages with 8 wpf C57BL/6N males for mating. At 27 28 hours zygote 39 43 hours 2 cell 68 70 hours 8 cell and 92 94 hours blastocyst post hCG administration the female mice were euthanized by cervical dislocation. Embryos were flushed from the reproductive tract into HEPES buffered CZB medium then transferred to acidic Tyrode's solution for a few seconds to remove the zona pellucida followed by three washes in M2 medium.	For zebrafish bulk zygote samples total RNA was extracted from 100 zebrafish zygotes using TRIzol™ Reagent and eluated in 100 μl of RNase free water. Then 10 μl and 5 μl samples were taken for 10 zygote and 5 zygote samples respectively and volumes were adjusted to 12 μl with nuclease free water. For zebrafish single zygote samples single zygote was manually picked and distributed into 12 μl of 1X Lysis buffer Takara. For the polyA selected RNA samples of mouse liver and embryonic stem cell WT and Mettl3 KO total RNA was extracted using TRIzol™ Reagent Thermo Fisher Scientific and PolyA+ RNA was selected twice by Dynabeads™ mRNA Purification Kit Thermo Fisher Scientific. For mouse embryonic stem cell samples the cells were sorted into 12 μl 1X Lysis buffer using BD FACSMelody™ Cell Sorter BD Biosciences. For mouse oocyte and embryo samples post three washes in M2 medium oocytes and embryos were manually picked and put into 12 μl 1X Lysis buffer. For picoMeRIP seq experiment NEBNext® rRNA Depletion Kit NEB was used to delete DNA and rRNA; RNA samples were sheared by sonication incubated with the anti m6A antibody from Millipore ABE572 and precipitated using ethanol. SMART Seq® Stranded Kit Takara Cat. # 634442 was used to prepare RNA sequencing library. Libraries were quantified with KAPA Library Quantification Kits Roche and the size distribution was checked using TapeStation D1000 ScreenTape Agilent Technologies.		developmental stage:Zygote\|molecule subtype:rRNA free RNA	GSM5599721	GSM5599721: ZF zygote IP 1cell Rep1; Danio rerio; RIP Seq	GSM5599721		1	For mouse liver total RNA was extracted using TRIzol™ Reagent Thermo Fisher Scientific and PolyA+ RNA was selected twice by Dynabeads™ mRNA Purification Kit Thermo Fisher Scientific.
